Robert Griffin III, who is coming back from a season-ending knee injury, is gradually seeing an increased workload in practice.

Coach Mike Shanahan said the quarterback had about ''16 or 17'' snaps Wednesday during 7-on-7 drills.

That's an increase from eight snaps the first few days and 10 snaps the next few days as Griffin works back into shape following reconstructive knee surgery.

Griffin got the extra work Wednesday even though the practice was held in steady rain on a field that's already showing considerable wear and tear. Several other players returning from offseason injuries were given the practice off.

Shanahan noted that he's still withholding Griffin from 11-on-11 drills.

Also, cornerback DeAngelo Hall is no longer wearing a boot on his sprained right ankle. He's expected to be sidelined at least a few more days.
